PGA of America Headquarters – Frisco, Texas

After all, what golfer wouldn’t feel at home in a facility that boasts an education center with advanced coaching facilities, an indoor short game practice area, 11 standard and four simulated hitting bays, and a practice green wired with motion-capture sensors? The creatively-designed space is illuminated largely by sunlight, and even includes a large video screen near the main entrance that uses RFID technology to welcome members by name.
